Develop a Java Library Management System with JUnit

Overview

By completing this course, learners will be able to analyze real-world requirements, design data models using Java POJO classes, implement menu-driven console applications, apply robust input validation with regular expressions, and develop automated unit tests using JUnit to ensure code reliability. This course guides learners through the end-to-end development of a Library Management System using core Java and JUnit, emphasizing practical implementation rather than theory alone. Learners gain hands-on experience in structuring applications, managing collections dynamically, handling exceptions gracefully, validating user input, and writing effective unit tests that support continuous quality assurance. What makes this course unique is its project-centric approach that mirrors real-world software development workflows. Instead of isolated examples, learners build a complete working system while adopting best practices in validation and testing. By the end of the course, learners will have a solid foundation in Java application development, improved problem-solving skills, and a portfolio-ready project that demonstrates practical knowledge of building, validating, and testing enterprise-style Java applications.

Syllabus

Building the Core of the Library Management System

This module introduces learners to the foundational concepts of building a Java-based Library Management System, covering project understanding, data modeling using POJO classes, collection management, menu-driven user interface design, and effective exception handling to ensure stable application behavior.

Validation, Testing, and Quality Assurance

This module focuses on strengthening application reliability by implementing input validation using regular expressions, integrating validation into the user interface, and performing automated unit testing with JUnit to ensure correctness and maintain continuous code quality.
